This paper emphatically introduces injection mould design of flagpole coor and CAD/CAM process of its mould parts.

本文着重介绍插旗杆座的注塑模设计及模具零件的CAD/CAM过程。

Some problems occurring in the forming process of the base of distorted pole and their solutions have been found through the simulation by DEFORM, a software that is able to perform plastic finite element analysis.

　使用塑性有限元分析软件DEFORM对扭杆座成形过程进行了模拟分析,找出了其在生产过程中出现的筋部充不满等问题的原因。

Elastic-plastic analysis and structure improvement for traction link base of locomotive bogie frame;

机车转向架构架拉杆座弹塑性分析及结构改进

Detailed structure design, calculation and analysis of locomotive traction link seat;

机车牵引杆座细部结构设计及计算分析

Based on the running environment, layout and structure of the traction link seat, reasons are analyzed theoretically for the breakage of the seat.

以SS7型电力机车运用环境、车体牵引杆座布置及具体结构为基础,从理论上分析了机车牵引杆座产生裂纹的原因,并对改进后机车牵引杆座进行了动强度测试验证。

It is proved that the linear displacement of linking bar supports and directional support paralleled the bar axis should not regard the unattached unknown node linear displacement of displacement method, and the linear displacement of linking bar supports and directional support un -.

针对用换铰法确定位移法中独立的未知结点线位移时遇到的问题,提出了对定向支座的换铰处理方法,论证了与杆轴平行的链杆支座、定向支座处的线位移不必作为位移法独立的未知结点线位移,与杆轴垂直或斜交的链杆支座、定向支座处的线位移一般要作为位移法独立的未知结点线位移,总结出了用换铰法确定位移法中独立的未知结点线位移的简单计算公式,使得换铰法不再受边界条件的限制,并通过实例计算得以验证。
